if one contact is not breaking before the other is making, that's a short circuit right there. No way to tell at a distance.

How? The Normally Closed aren't connected to anything. That's the sacrificial relay. It's just switches the element off and on.But first line looks like they'd love to sell you one at $40+. Great advice.

I didn't see anyone telling you to mind your own business in the thread, people were just making a point about how you entered this thread and dumped on their machines. Your observations might be absolutely correct, I have no idea, but the way you joined this discussion is probably what rubbed people the wrong way. It sounds like you know a good bit about espresso machines in general and I think most people are glad to get helpful advice from those who have the proper knowledge, but the advice wont be received well if it's presented in an off-putting manner.

Thanks for the information you provided. I hope I'll never need it but if I do have a problem I'm sure I'll review it.

I had the same problem with the valve sticking when I first got my machine. Jim from 1st line can email you instructions on how to clean it. Mine seemed to free itself up after I used the machine a couple of times and I never had to clean it. It has been fine ever since. Since then I have had a couple instances of thermosyphon stall where the boiler was hot by the group head was cool. That is easily remedied by a long flush of the group head.

Anyone want to send me instructions (tigermilk at sbcglobal dot net)? I have an email into 1st line but no response yet and I'm getting antsy. It's been a real pain over the past week - sometimes takes a good 10-20 seconds for water to come out of the head and of course it's lukewarm, so another 10-15 minutes just for a caffeine hit. Needless to say, the French Press has been getting plenty of use lately. Definitely seems like I've got a stall in there.

Anyone??? Still haven't gotten the machine functioning back to 100% normal yet. Just a bunch of flushing and still I get a "vapor lock". The other thing I forgot to mention is that since this potential thermosyphon stall started, my pucks have been coming out wet. Nothing has changed in my process in the last 12 months but the results certainly have.

I have had the cuadra for just over a week now. I am still working to get good shots. To be fair I have yet to have time to pull more than two in a row on any given day I am new to all this and am finding the learning curve to be challenging. I have lowered the boiler pressure this morning and that in itself did not make a noticeable difference. I am playing with dose and grind on my vario grinder and am still getting 10-15 sec shots aside from the one odd 2min shot. One question is I thought i had read that the cuadras were coming with an insulated boiler. I only see insulation between the water tank and the boiler.

There are a couple different models of the Cuadra. If you look on the 1st Line website, you will see the differences between them. Sounds like you do not have the Cuadra II which comes with the boiler fully insulated and the no burn steam/hot water arms.
